[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] Embodiment 1

[0035] The present invention discloses a sealing detection device for a vehicle door driver, wherein the vehicle door driver comprises a housing and a shaft body arranged in the housing, wherein the housing has a first sealing position, and a second sealing position is arranged between the shaft body and the housing, and sealing members are arranged at the first sealing position and the second sealing position to form a first sealing cavity between the first sealing position and the second sealing position. The sealing detection device comprises:

[0036] A sealing block, the sealing block can move along the axial direction of the shaft body and fit the housing so that a second sealing cavity is formed between the second sealing position and the sealing block; the sealing block is provided with a vent hole for detecting air tightness;

[0037] A clamping member, wherein the clamping member can clamp the shaft body; the clamping member can drive the shaft body to move axially to connect the first sealing cavity and the second sealing cavity.

[0038] The clamping member is configured to pull the shaft body to connect the first sealing cavity and the second sealing cavity when a first sealing position is detected.

[0039] In this embodiment, only one inspection station is provided, and a sealing block and a clamping member are provided at the inspection station.

[0040] When detecting the first sealing position, the sealing block moves downward to fit with the shell, so that a second sealing cavity is formed between it and the second sealing position; then the shaft body is pulled by the clamping member to drive the sealing member on the shaft body to move, thereby opening the second sealing position and connecting the first sealing cavity and the second sealing cavity. At this time, air is ventilated into the vent hole to detect the air tightness of the first sealing position.

[0041] When detecting the second sealing position, the clamping member does not pull the shaft, the seal at the second sealing position no longer moves, and the sealing block moves downward to fit with the shell to form a second sealing cavity between it and the second sealing position. At this time, gas is introduced into the vent hole on the sealing block to detect the air tightness at the second sealing position.

[0042] In this way, by selectively pulling or not pulling the shaft, the air tightness of the first sealing position and the second sealing position can be detected at the same end of the door driver, without placing the detection devices at the two ends of the door driver for separate detection, thereby improving the efficiency of batch detection.

[0043] It should be noted that since the shaft is long and the clamp is large in size, it is difficult to place the entire shaft and the clamp in the sealing block at the same time, so the shaft or the clamp will pass through the sealing block. Therefore, in order to implement the solution in this embodiment, it is necessary to ensure the sealing between the shaft or the clamp and the sealing block under the premise that the shaft or the clamp can slide relative to the sealing block.

[0044] Embodiment 2

[0045] Please refer to Figure 1-Figure 5 The present invention discloses a sealing detection device for a vehicle door driver, wherein the vehicle door driver 400 comprises a housing 410 and a shaft 420 disposed in the housing 410, wherein the housing 410 has a first sealing position, and a second sealing position is disposed between the shaft 420 and the housing 410, and sealing members are disposed at both the first sealing position and the second sealing position to form a first sealing cavity between the first sealing position and the second sealing position, and the sealing detection device comprises a first detection station 100 and a second detection station 200:

[0046] A first sealing block 110 and a clamping member 120 are provided at the first inspection station 100. The first sealing block 110 can move along the axial direction of the shaft body 420 and fit the housing 410. The first sealing block 110 is provided with a vent hole for detecting air tightness and a through hole for allowing the shaft body 420 to pass through. The clamping member 120 can clamp and drive the shaft body 420 to move axially to the second sealing position, and the sealing member moves between the shaft body 420 and the first sealing block 110, so that a third sealing cavity is formed between the first sealing position, the sealing member and the shaft body 420.

[0047] A second sealing block 210 is provided at the second detection station 200. The second sealing block 210 can move along the axial direction of the shaft body 420 and fit with the shell 410, and the shaft body 420 is enclosed in a second sealing cavity formed between the second sealing position and the sealing block; the second sealing block 210 is provided with a ventilation hole for detecting air tightness.

[0048] It should be noted that in the first embodiment, it is necessary to ensure good sealing between the sealing block and the shaft body 420 or the clamping member 120 under the premise that the shaft body 420 or the clamping member 120 can slide relative to the sealing block. Based on this, the present application provides a second embodiment, in which a first detection station 100 and a second detection station 200 are set to detect the first sealing position and the second sealing position respectively.

[0049] Specifically, at the first inspection station 100, a first sealing block 110 and a clamping member 120 are provided. The first sealing block 110 moves downward to fit with the housing 410, so that a second sealing cavity is formed between the first sealing block 110 and the second sealing position; then the shaft 420 is pulled by the clamping member 120, driving the seal on the shaft 420 to move, thereby opening the second sealing position, connecting the first sealing cavity and the second sealing cavity, and then ventilating the vent hole to detect the air tightness of the first sealing position. When the shaft 420 is pulled, the seal on the shaft 420 (i.e., the seal at the second sealing position) can be pulled together, so that the seal leaves the original position and moves between the first sealing block 110 and the shaft 420, so that the first sealing block 110 and the shaft 420 are sealed by the seal.

[0050] At the second inspection station 200, only the second sealing block 210 is provided, and the clamping member 120 is no longer provided. The second sealing member is pressed down to fit with the housing 410, and then gas is introduced into the vent hole to detect the air tightness of the second sealing position.

[0051] As can be seen from the above, at the first inspection station 100, the seal between the first sealing block 110 and the shaft body 420 can be achieved by the seal at the second sealing position, and no additional seal is required. At the second inspection station 200, there is no need to pull the shaft body 420, so there is no need to set the clamping member 120, and the second sealing block 210 can cover the entire shaft body 420, so there is no need to consider the sealing between the shaft body 420 and the second sealing block 210.

[0052] It should be noted that the present application is to test the airtightness of the seal at the first sealing position and the second sealing position. As for the seal itself, it has been tested and qualified before assembly. Therefore, as long as the processing accuracy of the first sealing block 110 is guaranteed, when the seal is between the first sealing block 110 and the shaft 420, there should be good airtightness.

[0053] Furthermore, a clamping assembly is provided at both the first inspection station 100 and the second inspection station 200 . The clamping assembly includes at least two clamping cylinders that are arranged opposite to each other. The clamping cylinders are used to clamp the side wall of the shell 410 .

[0054] The clamping assembly is provided to clamp the door driver 400 at the side, so as to position and lock it and prevent it from shaking during the detection process.

[0055] Furthermore, a moving component is also included, which includes a slide rail 300 and a carrier 310 for supporting the door driver 400. The carrier 310 can slide along the slide rail 300 to allow the door driver 400 to switch between the first inspection station 100 and the second inspection station 200 at will.

[0056] By setting a moving component, the door driver 400 only needs to slide in a single direction to switch between the first inspection station 100 and the second inspection station 200 to respectively inspect the sealing properties at the first sealing position and the second sealing position.

[0057] Furthermore, a fixing frame 500 is also included;

[0058] The first inspection station 100 is also provided with a first sliding frame 510 and a second sliding frame 520. The first sliding frame 510 and the second sliding frame 520 can both slide in the height direction relative to the fixed frame 500; the clamping member 120 is arranged on the first sliding frame 510; and the first sealing block 110 is arranged on the second sliding frame 520.

[0059] Furthermore, a third sliding frame 530 is further disposed on the second inspection station 200 . The third sliding frame 530 can move along a height direction relative to the fixed frame 500 . The second sealing block 210 is disposed on the third sliding frame 530 .

[0060] Specifically, the first sliding frame 510 , the second sliding frame 520 and the third sliding frame 530 are respectively provided with driving cylinders for driving, so as to realize the up and down movement of the clamping member 120 , the first sealing member and the second sealing member.

[0061] Furthermore, both the first sealing block 110 and the second sealing block 210 are provided with sealing rings.

[0062] The first sealing block 110 and the second sealing block 210 are provided with sealing rings. When the first sealing block 110 and the second sealing block 210 move downward to fit with the housing 410 , the sealing rings can be squeezed to achieve sealing between the first sealing block 110 / the second sealing block 210 and the housing 410 .

[0063] Furthermore, the clamping member 120 includes two clamping arms 121 that can move closer to or farther away from each other, and a clamping cylinder for driving the two clamping arms 121 to move closer to or farther away from each other.

[0064] Furthermore, it also includes an airtightness detector, which is connected to the vent hole through an air pipe.

[0065] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0066] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0068] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
